SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 262,162, dated August 1, 1882.

Application filed July 20, 1881.

To all whom it may concern:

Be it known that I, GEORGE W. WARREN, ofBristo in the county of Elkhart and State of Indiana, have invented a new and-useful Improvement in Vehicle-Springs, of-which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specification.

This invention relates to side-springs for vehicles; and it consists of asuspension-spring, which is adapted to be sprung open instead of being closedwhen weighted.

In the drawings, Figure l is a plan view of the runninggear of a vehicle without the wheels, and Fig.2 is a side elevation of the same.

The spring is formed of two main leaves, a

a, having slight curves at the center and placed together in the manner of an elliptical spring, except that the ends lie in parallel planes against each other, while the ends of one ofthe leaves, which islonger than the other, are bent over the ends of the other leaf, so as to form three thicknesses, through which a bolt is passed and secured by a nut. On the inner sides of the main leavesa a are secured the single lap leaves I) b, which are made shorter than the main leaves and held in contact therewith throughout their entire length. For ordinary purposes the single lap-leaves will be sufficient, but additional lap-leaves may be used, if desired.

It is evident that the ends of the main leaves may be secured together in various other ways than that above described, so that the said leaves shall be firmly held together with the bodies of the leaves close to each other, only sufficient space being left between them to accommodate thelap-leaves and the clips or bolts, by which the spring is seemed to its connections.

1 am aware that an elliptical spring has been used, which has its main leaves secured rigidly together, end to end; but such a spring has never before been adopted for use as a suspensionvehicle-spriuglikemine. Inmyspringthe main leaves are placed as near together as possible, and are re-enforced or strengthened on the (ModeL) inner sides with lap-leaves, so that they shall be adapted for supporting an expanding, instead of a compressing, weight. Heretofore curved braces have been arranged inside the main leaves with a space intervening between them and the main leaves, and adapted to be sulr jected to tensile strain only when the main leaves are com pressed together. Such a spring, however, is not adapted to be used in cases where the main leaves are expanded apart instead of being compressed together.

. The springis applied to use in the following manner: The upper main leaf, a, is secured in contact with the under surface of the side bar, 0, of the vehicle by bolts or clipsc, which may be arranged at any desired intervals apart, according to the degree of tension required. The ends of the spring are left free and the bed of the vehicle is supported upon bars 62 or springs, as the case may be,'which are supported upon or from the lower main leaf, to. With this construction the bed is suspended by the spring, and the weight of the bed or load tends to open the spring, instead of closing it, as in the case of most elliptical springs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A suspension vehicle-spring composed of two main leaves having their ends rigidly secured together, in combination with the lapleaves made shorter than the main leaves and secured in contact with the inner sides of the main leaves, substantially as shown and described.

2. The vehiclespring composed of the main leaves a a, having their ends rigidly secured together, in combination with the side bar, 0, to the under surface of which the upper main leaf is secured, and the bars 02, connected to the lower main leaf of the spring for supporting the bed of the vehicle, substantially as shown and described.
